jquery - How to sort dates by asending order. Dates are like dd/mm/yyyy (31/12/2015) or (dd-MMM-yyyy) format -

i have scenario need sort dates different format dd/mm/yyyy (31/12/2015) , mm/dd/yyyy (12/31/2015).

for mm/dd/yyyy (12/31/2015) using sortedkey = sortedkey.sort(function(a,b) { return - b;}) how can sort format mm/dd/yyyy

javascript not work dates in dd/mm/yyyy format.

if had dates in mm/dd/yyyy format, able convert strings date , compare:

var arr = ['01-01-2015', '03-03-2015', '07-30-2015', '12-30-2014']; // mm-dd-yyyy    arr.sort(function(a, b) {    var adate = new date(a);    var bdate = new date(b);      return (adate < bdate ? -1 : 1);  });    document.write(arr.join("<br/>"));

the best way solve problem change format of dates.

however, if cannot change format of dates, can use hacks parsing using regular expressions:

function parse_ddmmyyyy(str) // example: str = '07-30-2015'  {    var numbers = str.match(/\d+/g); // numbers [7,30,2015]    return new date(numbers[2], numbers[1]-1, numbers[0]); // new date(2015, 6, 30)  }    // dd-mm-yyyy (dd/mm/yyyy)  var arr = ['01-01-2015', '03-03-2015', '30-07-2015', '30/12/2014', '18/11/2016', '03-11-2014', '02/01/2015'];     arr.sort(function(a, b) {    var adate = parse_ddmmyyyy(a);    var bdate = parse_ddmmyyyy(b);      return (adate < bdate ? -1 : 1);  });    document.write(arr.join("<br/>"));

this work both dd-mm-yyyy , dd/mm/yyyy, mixed.
